  • The Relationship between Clinical Characteristics and Pathology Findings of Solitary Pulmonary Nodules

    ObjectiveTo elucidate the relationship between clinical characteristics and pathology findings of solitary pulmonary nodules (SPN). MethodsA retrospective cohort study was carried out on 231 SPN patients pathologically confirmed between January 2009 and December 2013 in Nanjing General Hospital of Fuzhou Military Command and Fuzhou Second Hospital. Using pathological results as reference standard, the sex, age, smoking history, smoking amount, quit smoking history, and extrapulmonary malignant tumor history were compared between the SPN patients with different pathological type. ResultsFemale and age were positively correlated with the probability of malignancy in SPN with correlation coefficients as 1.090 and 0.063 respectively. Extrapulmonary malignant tumor history, smoking history, smoking amount, quit smoking history did not show significant relationship. Gender was a factor that affects pathological types of SPN. Female patients were in higher risk than male patients to have precancerous lesions, pulmonary aspergillosis, pulmonary sclerosing hemangioma, adenocarcinoma. Male patients had higher risk suffering from pulmonary tuberculosis, pulmonary cryptococcosis, squamous cell carcinoma, adenosquamous carcinoma, inflammatory pseudotumor and metastases. Distribution of SPN pathologic types in each age group was similar. Most patients who had precancerous lesions, pulmonary hamartoma, pulmonary aspergillosis, pulmonary sclerosing hemangioma, adenocarcinoma and inflammatory pseudotumor were not smokers. ConclusionsGender and age are valuable in distinguishing benign SPN from malignant SPN. Pathologic types of SPN are related to patients' gender and smoking history.
